Abstract

A technique is described whereby a laser engraver is incorporated into an assembly line fixture, so as to provide proper identification to production parts as the parts are processed along assembly line workstations. The fixture includes all required safety features and has the ability to easily change engraving nomenclature. In prior art, inking was used as the identification process of production parts. The inking procedure encompassed changing of a cliche, inking, cleaning and storing of ink cartridges, as required. The laser engraving fixture, described herein, eliminates the messy ink transfer method and storing requirements, while providing all radiation and other safety requirements, so as to attain high quality, high production nomenclature engraving.

Laser Engraving Fixture for Automatic Assembly Lines

A technique is described whereby a laser engraver is incorporated into an assembly line fixture, so as to provide proper identification to production parts as the parts are processed along assembly line workstations. The fixture includes all required safety features and has the ability to easily change engraving nomenclature. In prior art, inking was used as the identification process of production parts. The inking procedure encompassed changing of a cliche, inking, cleaning and storing of ink cartridges, as required. The laser engraving fixture, described herein, eliminates the messy ink transfer method and storing requirements, while providing all radiation and other safety requirements, so as to attain high quality, high production nomenclature engraving. The laser engraving fixture consists of laser marking unit 1, as shown in the figure, for setting the proper nomenclature when engraving the part identification at the assembly station. It is easily programmed by a set of thumb wheel switches located on a separate operator's panel. Umbilical cable 2 consists of a thirty-foot- long cable so as to connect laser marking unit 1 to a laser control unit located away from the engraving fixture. Mounting support and adjusting unit 3 features a vertical and horizontal adjustment for setting the proper focal length and printing position. Laser engraving head 4 performs the actual engraving identification onto the pa...
